ICE-PLOW.

SPECIFICATION forming part of Letters Patent No. 596,348, dated December 28, 1897. Application filed February 4, 1897. Serial No. 622,060. (No model.)

T0 at whom, it may concern:

Be it known that LVVILLIAM E. 'WOOD, of Arlington, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Ice-Plows, of which the following is a specification.

Ice-plows are frequently made with a guideplate which is substantially parallel'with the blade of the plow and at such a distancetherefrom as represents the width of the strip of ice to be cut. After one groove has been cut by the plow the guide-plate is placed in that groove and runs in it while the next groove is being cut, and hence determines the position of that next groove, and consequently the width of the strip of ice.

Plows have been made reversible-that is to say, the bars which carry the guide-plate referred to have been hinged to the top of the plow, so that the guide-plate may be used either on the right-hand or the left-hand side of the plow. A reversible plow, however, in which the guide-bars are at an angle to the surface of the ice, so far as I know, has never been made so that the guide-plate may be ad-' justed toward or from the blade without tending to throw the plow out of plumb.

My invention consists in a plow which is not only reversible in the manner above described, but upon which the guide is adjustable, so that the plow may be very easily and readily adjusted to cut furrows of any given distance apart without throwing the plow out of plumb.

It also consists in certain details of construction described below, applicable also to a nonreversible plow.

My invention will be understood by reference to the drawings, in which- Figure 1 is a side view of a plow embodying my invention, Fig. 2 being a plan, and Fig. 3 a section, on line 3 3 of Fig. 2.

A is the body or backbone of the plow, from which projects downward the necessary sawteeth B. From the rear end of the part A project upward the handles 0 in usual manner. To the top of the body of the plow'A are hinged the bars D E, their hinges d 6 being of such construction that the guide-plate F can be swung from the position shown in full lines in Fig. 3 to the position shown in dotted lines in the same figure. The guide-plate F is provided with two sleeves ff, containing square or angular passages. These sleeves are attached to the guide-plate by bolts f and through the sleeves and the guide-plate pass the bars D E. These bars are so shaped in cross-section as to fit the angular passages in the sleeves ff.

Each sleeve ff is provided with a transverse hole, and the outer end of each bar D E is provided with a series of adjusting-holes h, (see Fig. 3,) each adapted to register with the transverse'hole in its sleeve f f. A bolt d 6 passes through one of the transverse holes in the sleeve ff and one of the holes h in one of the bars D E, and thusholds the guide-plate in place.

The end of the bolt 6, which passes to the rear of the plow, is hook-shaped, (see Fig. 2,) and the point of the hook when set up by its nut forms an eye into which hooks the front end of the guide-handle G G. In practice I provide a second hole in the side of the sleeve f to receive the end of this hook, so that when its nut is set up tight it passes through the sleeve and binds against the bar E, binding it in turn against the opposite side of the passage through the sleeve f.

The guide-handle G G is adjustable in length, as shown in Figs. 1 and 2, its lower end G being adapted to slide in a sleeve in the upper end G, which carries the handle proper, and being preferably held in place by a set-screw g. The upper end G of this guiderod handle is notched at g to hook onto the cross-bar G. e

To adjust the plow, it is only necessary to remove the bolts d 6, push the guide-plate a proper distance upon the bars D E, and then replace the bolts d e, the set-screw g being first released, so that the lower part G of the guide-handle may slide freely in its sleeve or socket. After the guide has been adjusted in place a turn to the set-screw 9 will fix the length of the handle. This is a simple mode of adjustment which answers the purpose very well. The guide can at any time be swung over to the opposite side of the plow, thus changing the plow from right to left handed. The angular passages in the sleeves and the corresponding shape of the bars result in a guide-frame so stiif that it can easily be thrown over without racking it.

I have shown the simplest form of adj ustment which is now known to me, and such a form of adjustment is extremely useful, because it interferes in no way with the changing of the plow from a right to a left handed plow, as above described. Moreover, when the guide-handle is made adj ustable and connected to the bar E near the guide-plate F, so that it may be adjusted along the bar E, for example, by being attached to the sleeve f, as shown, it not only serves to throw the guide over from left to right, or vice versa, but, what is more important, it serves to hold the plow so that its blade is perpendicular to the plane of the ice. When in use, the guide sinks to the bottom of its groove or furrow, and if the length of the guide-handle has not been properly adjusted the guide will pull the blade out of plumb if the guide-handle rod is too short, or push it out of plumb if it be too long. By making it adjustable in length any such difficulty can be avoided. For this reason it is desirable to make ascale on the lower part of the guide-handle, so that the user can tell exactly how much to lengthen or shorten it for a given length of the guidebar. If preferred, the adjustment may be made by providing a number of notches g upon the guide-handle, any one of which may be hooked over the cross-bar O, or the adj ustment may be made by a movable notched piece adj ustably attached to the guide-handle.

I have used the term plow in the above description, but it is evident that that term is inclusive of the tool known as a marker, which is like a plow, except that the blade does not cut as deeply, and which also is often used with a guide, and having a cuttingblade is used to mark out the strip of ice to be cut.

It will be fully understood that an adjustable guide, such as I have described, is equally 5 useful in such a construction.

\Vhat I claim as my invention is-- 1. The reversible ice-plow above described provided with bars D, E, hinged to the plow and carrying at their outer ends a guide-plate adjustable thereon, and a guide-handle, the lower end of which is adjustably connected to one of said bars, all as set forth.

2. In an ice-plow having an adjustable guide-plate, the guide-handle G adjustable in length, the front end thereof being connected to the guide-plate as described, all as and for the purposes set forth.

3. The ice-plow above described having an adjustable guide-plate, said guide-plate being provided with sleeves projecting at right angles therefrom and said plow being provided with rods adapted to travel in said sleeves and be locked therein, in combination with the bolt c shaped as shown and an adjustable guidehandle, the lower end of which is attached to the eye formed in said bolt 6 and the upper end of which is adjustably connected to the handle of the plow, as set forth.

at. The plow above described, having a guide'plate provided with sleeves f, f each having an angular passage through it, in combination with bars D, E each shaped in crosssection to fit its sleeve 1'', f and hinged to the back of said plow and a guide-handle attached to one of said sleeves f whereby is formed a rigid reversible frame capable of operation by said guide-handle, as set forth.

5. In an ice-plow of the kind described, the combination of the sleeve fattached to the guide-plate and carrying one end of a bar and the hooked bolt 6, the shank of which passes through said sleeve and bar and hooked end of which passes back through said sleeve and impinges against the surface of said bar, thus causing a solid contact between said bar and sleeve, all as set forth.

In witness whereof I have hereunto set my hand this 1st day of February, 1897.

IVILLIAM E. NVOOD.
